To all whom it may concern.

Be it known that I, ICARIi H. BEISWENGER,

a citizen of the United States, residing at Jackson, in the county ofJackson and State of Michigan, have invented certain new and usefulImprovements in Take-up Devices for Moving-Picture-Film Reels; and I dodo clare the following to be a full, clear, and

exact description of the invention, suchgas willenableothers skilled inthe art to which it appertains to make and use the same.

This invention relates to an" improved take-up device for use inconnectionwith a reel to have a strip of movingpictiue film woundthereon and one object of the invention is to provide a device whichwill control the speed of rotation of the reel or spool upon which thefilm is being wound, the

speed of rotation gradually changing and becoming slower as the film iswound thereon.

Another object of the invention is to provide a device of the characterdescribed which is so constructed that it may be mount ed externally ofthe casingto receive the drum or reel, a sliding dlsk belng provided forextending through the slot in theca'sing and engaging a disk carried bythe drum mounting shaft.

Another object'of the invention is to 'so' construct this devicethat'the shaft carrying the disk and druinmay be slidably as well asrotatably mounted and the shaft engaged by a'spring which will move theshaft longitudinally to hold the disk thereof in tight engagement withthe movable friction wheel or disk upon the driven-shaft carried by the:

device.

Another object of theinvention is to pro{ vide a deviee'of thecharacter'described in which the initial speed of the drum maybecontrolled by adjustmenfi'of the friction disk which engages the diskmounted within the casing. e

Another object of the invention is to provide a device which will besimple'in constructionand very efiicientin operation.

This. invention is illustrated in. the accompanying drawings, wherein:

improved device in useQ Figure 2'is a longitudinal sectional viewthrough the structure of-Fig. 1.

Figures 3, 4 and 5 are fragmentary sectional views taken along the line33, 4-4 and 5-5 of Fig. 1. I I This device is to be mainly positionedout Figure'l is'aside elevation showingthe side the casing 1 in whichthe spool or drum 2 for receiving-the film 3 is placed; The dc; woe isprovided with abearing bracket'4 having across head 5 at one endwhichextends transverselyof the casing and 1s provided' with a neckextension '6 to receive the plunger -7 which extends'through this neckand head and throughan opening in the casing intothe interior thereof.The plunger is provided at its outerend' with an en'- 1 largemen't orhead 8 and, at its inner end is connectech with the axle: of a roller9', the.

roller being. a double rollerand positioned" upon opposite sides" ofthis plunger and adapted to engage thefilm which is wound uponthe hub ofthe drum 2. The bracket e hasits end 'por-tions'provided with slots 10and 11 and intermediate its length has been provided with a sleeve 12which terminates in a neckextenslon 13carry1ng at 1ts outer end; a heador bearing 14. The shaft 15 'for the spool ordrum 2 is mounted in theneck and head 14 and is permitted of rotary and sli.ding-'movement. Thedrum is removably mounted upon the inner end portion of this A shaft andisheld thereon by means of a key 16 so that the shaft and drum willrotate together. A disk 17 isfirlnly mounted upon thesha-ft within thecasingadjacent the wall thereof vwhich has bee n provided with a slot 18for registering with the erot c and it will thus "beseenthat whenthisdisk is rotated,

be *yieldably held against movement in an opposite direction and thedisk 17 will be held in tight contacting engagement with a friction disk-22"which is slidably mounted upon a shaft 28 journalled in bearings 24and 25 of the'bearing bracket. This disk 22 is held against rotary"movement :upOn the shaft 23 by means of akey 26; but may slide freelythereon and is providd v shoulder extension 27 having a groove 28 formedtherein to receive the fork 29 which is securely but releasably and thusadjust ably mounted upon a rod. This rod 30 is secured "in an openingformed in an up that the drum or spool '2 will at all times be standingear 31 carried by a sleeve 32 which is releasably secured upon the shaft23 beyond the abutment collar 33 which is releasably secured thereon andadapted to engage the bearing 2 1 and prevent longitudinal in a bearing39 of the bearing bracket and when the shaft 38 is rotated, rotarymovement will be transmitted to the shaft 23.

lVhen this device is in use, the disk 17 is rigidly secured upon theshaft 15 within the drum housing 1 and the plunger 7 and the roller 9engage the hub upon which the strip of film 3 is to be wound. The fork29 will be fixed upon the rod 30 so that the disk 22 will be positionedto engage the disk 17 at the proper point when starting ,to wind thefilm upon the hub of the spool or drum and the arm 34 will be tightenedupon the plunger 7. Thespring 21 through engagementwith the collar 20moves thershaft 15 to hold the disk 17 in tight frictional e'n-*gagementwith the disk As the shaft 38 rotates from an upper drumnotshown, the

rotary movement is transmitted to the shaft:

23 and through the medium of the disks .22

l and 17 the lower spool or drum rotates. As

the film winds upon this lower spool or drum, thethickness of thefilmfwoundupon the hub thereof increases andtheplunger 7 gradually movesoutwardly. This outward movement of the plunger causes the sleeve 32 toslide longitudinally upon the shaft23, and as this sleeveor carriermoves, the rod 30 also moves longitudinallyvof'the shaft. Since the forkis rigid upon this rod 30, the

- disk 22 ismoved towardsthe outer periphery of the disk 17 and sincethe disk 17 is dr ven from the disk 22, the speed at which the disk 17and drum2 rotates; will gradually become slower. it will thus be seenrotated at the proper rate of speed to wind thefilm upon the spool asitmoves from the upper spool not shown. Therefore, there will be noslack in the film and further there .will be no excessive strain orstretching ap plied to this stripof film. It will thus be seen that astrip of film maybe wound" from an upper spool "upon the lower spoolwithout danger ofthe film being torn or otherwise damaged.
